Application filed October 11.1912. Serial No. 725,146.

To all whom it may concern:

Be it known that I, TEOFIL Gnzrwinnsni, a subject of the Czar of Russia, residing at Penfield. in the county of Clear-field and State of .lIennsyl 'ania, have invented certain new and use t'ul Improvements in Window-S a'ee11s, of which the following is specification, reference being had therein to the accompanying drawing.

This invention relates to window screens, and the object of my invention is to locate a spring roller in the sill of a window frame and attach to said roller and wind thereon n flexible interwoven wire screen that is also attached to the lower rail of one of the win- (low sashes, whereby when the sash is raised the screen is pulled into position to screen the window and prevent flies or other in sects from entering it compartment in connection with which the screen is used. I attain the above object by a mechanical construction that is simple, inexpensive to manufacture, durable, and easily embodied as part of the window frame when said frame is constructed.

My invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing Wherein:

Figure 1 is a front elevation of a window frame in accordance with this invention, Fig. 2 is a vertical sectional view of the same, and Fig. 8 is an enlarged detail sectional view of a portion of a window sash, showing the manner of attaching toe screen thereto.

To not my invention into ractice, 1 provide the l of :1 window trains 2 with n longitudinal slot 3. Secured to the bottom of rho sill l, beneath the slot 3 is e longitudinal hous ng and located in said housing' is a spring roller 5 of the ordinary and well known curtain-shade type, this roller, other than its specific use forming no part of this invention.

Attached to and wound upon the roller 5 is a. screenfi preferably made of interwoven wire, said screen extending through the slot 3 end having the upper thereof clamped between longitudinal \arallel flanges 7 ofa hold fast plate 8 secured by screws 9 or other fastening means to the bottom rail 10 of a sash ll. The plate 8 is made of a single piece of material doubled upon itselfwith the longitudinal edges of the plate bent to provide the flanges T and these flanges are connected together by rivets 12 or other fastening means that firmly hold the upper edge of the screen 6 between said flanges. The flanges '7' the slot 3 when the sash 11 is lowered; th' screen 6 being wound upon the roller, which is invisible and does not mar the general appearance of the window. When the sash 11 is raised the screen 6 is immediately shifted into position to prevent flies and other sects from passing through the openwindow.

What I claim is:--

In a window screen combination with c. window sash and frame, a hold-fast plate comprising members secured to the bottom edge of said sash and having portions bent downwardly to provide longitudinally extending vertical flan es disposed centrnlly with respect to sai Window snsh, said flanges opposing each other, and together being the same width as the bottom said window sash and being secured. th' etc, a screen having its upper end positioned lsetween said flanges, rivets extending through said flanges and screen for securing the screen to the plate whereby screen coupled to the sash when the lets inernhe. s are secured thereto, the said screen hciuug its lower end connected to spring roller and the said roller being disposed Within longitudinal housing in a window being adapted to wind and unwind roller when the sash is vertically moved.
